Returns SET OF ``(seq, node, cost, agg_cost)``

============= =========== =================================================
Column           Type              Description
============= =========== =================================================
**seq**       ``INTEGER`` Row sequence.
**node**      ``BIGINT``  Identifier of the node/coordinate/point.
**cost**      ``FLOAT``   Cost to traverse from the current ``node`` to the next ``node`` in the path sequence.

                          - ``0`` for the last row in the tour sequence.

**agg_cost**  ``FLOAT``   Aggregate cost from the ``node`` at ``seq = 1`` to the current node.

                          - ``0`` for the first row in the tour sequence.
